    I have the white foam on the 7020-06427-301-0 board. so i took the unit apart and got to the heat sink. I do not see anything labeled 7815, 7915, or 7805. I have 6 sk D2560s, 7 sk B1647 , and 7 smaller ones D947F and one sharp PQ20RX11. Which ones do i need to replace? I am planning on going to radio shack to see if they have these if so i will replace all of them if not where should i get them online? Also do i need to replace the silver oscillator (WIN 3.579545mhz (15PF)) and a green resistor (mine is J222) where the white foam is?

    Ok i see my problem. I was looking at the huge heat sink. those 3 are not on the main one they are on 2 smaller heat sinks near where the power stuff plugs on to the board. Radio shack didnt have anything i needed. I found that Jamesco electronics has a web page, so ill just order them from there. I will let you guys know if it fixes it.
